Supernovae, neutron star collisions and active galactic nuclei are among the most energetic phenomena in the known universe. These violent explosions produce high-energy gamma rays and cosmic rays, which ...

University of Groningen scientists have developed a molecular sensor to measure 'crowding' in cells, which reflects the concentration of macromolecules present. The sensor provides quantitative information ...

One of the problems in the high-tech field of visible light communication (VLC) - or using light to send data wirelessly - is decidedly low tech: The data transmission stops whenever the light is blocked ...

For almost 400 years, mercury gauges have prevailed as the most accurate way to measure pressure. Now, within weeks of seeing "first light," a novel pressure-sensing device has surpassed the performance of ...

Optical emission spectrometers are widely used in the steel industry but the instruments currently employed are relatively large and bulky. A novel sensor makes it possible to significantly reduce their size ...

SAM Labs, a London based startup has created a Kickstarter project that looks to take do-it-yourself project making and teaching how to program digital hardware, to a new and simpler level. Their SAM kits ...

Copious corn growing in tiny backyard plots? Roses blooming in December? Thanks to technology that the University of Wisconsin-Madison's Richard Vierstra has been developing for years, these things may soon ...

A combined team of researchers from Harvard and MIT has added a light sensor to a fly-sized drone to allow it to maintain stabilization and is the first known use of onboard sensors at such a small scale. ...

Rotary sensors can help determine the position of a moveable body in relation to an axis. They are essential to the smooth running of car engines in the automotive industry, for example. Fraunhofer researchers ...

(Phys.org) —Most of today's digital cameras achieve color by using red, green, and blue Bayer color filters through which light passes on its way to the camera's image sensors, which then convert the light ...

Researchers from North Carolina State University have developed a new processing technique that makes light emitting diodes (LEDs) brighter and more resilient by coating the semiconductor material gallium ...

(Phys.org) —Volvo Cars announced on Monday its work on a driver sensor system that can tell if the driver is alert, distracted, or even nodding off. The idea is to provide a safety system, where, on detection, ...
